How to set webpack output path to write to existing directories on multiple entry points?

Question

webpack

There is approximately such a config (I give a fragment)

const config = {
  entry: {
    '/green/': ['./green/theme-green/js/src/index.js', './green/theme-green/less/style.less'],
    '/red/': ['./red/theme-red/js/src/index.js', './red/theme-red/scss/main.scss']
  },
  output: {
    path: path.join(__dirname, '/dest/'),
    assetModuleFilename: 'assets/[hash][ext]',
    filename: '[name]combine.js',
    publicPath: ''
  },
  module: { 
  // 
  }
}

In addition, there are green and red folders in the root (with sources)
How to set up paths in the path to write to them (according to the entry point, for green - green / dest / ... and for red - red / dest / ... )

To be more precise: how to get the name of the entry point in path?
